m102404: Freeze-heat fit? Wow interesting option... think I might do just that. But what material should the ring be? A silver ring would just melt under a torch wouldn't it? Hard to find alumnium jewelry around. Steel is too hard a material on the alumnium slide?
I would drill a hole into the ring.. if I had the tools to do so. If only I had access to machining tools, Ill be making my own comp to fit.
Mr.Hitman: Hey thanks appreciate that!
Yeah well I went to all the major shops Dentrinity, Tokyo Model, Guns 'n'Guys, Armed Forces, even the elusive Redwolf which only opens on alternate Saturdays until 1pm.. all say I'm f**ked please buy a new slide.

I'll try not to until I screw up something else. Then I'll do what they say.
